TWIN-LABEL PUNCHER.

Application filed April 3, 1925. Serial No. 20,330.

This invention relates to improvements in label cutters, and it is the principal object of my invention to provide a label cutter or punching device for cutting a double stack of labels from sheets in one operation, and for simultaneously removing the waste material by means of a specially constructed cutter adjusiable and working on a fibrous base.

Another object of the invention is the provision of a means for adjusting the cutting or punching devices relatively to said waste remover and to said fibrous plate.

A further object of the invention is the provision of a waste remover of peculiar con struction adapted to be adjusted and eifec tively preventing the clogging of the apparatus and the hollow punching tools by the wasle paper out from the sheets from which the labels are punched.

These and other objects and advantages of my invention will become more fully apparent as the description thereof proceeds, and will then be specifically pointed out in the appended claims. 7

Figure 1 is a front elevation of a labelcutting device embodying the improved features constructed according to the present invention.

Figure 2 is a rear end view thereof.

Fig. 3 is a bottom plan view of the cutter constructed according to the invention.

Fig. 4 is a cross-section on line 44 of Figure 3.

Fig. 5 is a modified form of waste remover in side elevation.

Fig. 6 is a bottom plan view of a modification of the cutting apparatus.

0 Fig. 7 'is a fragmentary sectional View of a waste remover adjusting and operating means.

A machine of suitable construction inchiding a cross-head 10 to which the hollow suitably shaped cutting dies or plunger-knives 11 and 12 are secured by means of a boss 13, has attached thereto the pitman 14 operated from a crank shaft 15, journaled in bearings 16 and carrying at one end the fly-wheel 17 50 The entire so far described mechanism is mounted on a base 18.

.The hollow cutting dies 11 and 12 are mounted in any suitable manner as for stance; described co-pending applies ticn, Ser. #129,283, filed March 30, 1925, and

are equipped with superposed adjustable discharge chutes 19 and 20.

The waste remover in this form of our invention is supported upon a base 21, and comprises a plate 22 of fibrous or other suitable material having lateral flanges 23, 24 to the outer edges of which shoes 25, 26 are attached, which glide in grooves 27, 28 of the base plate 21. Theseshoes are provided with elongated slots 29, 30, 31 and 32. in which the adjusting screws 33 are arranged adapted to be operated by means of wing nuts 34 or the like. The lower ends of the shanks v5, 36 of the waste remover blade 37 of substantially stretched or elongated U-shape are secured to the shoes 25, 26 between each pair of openings therein.

In the form of waste remover blade shown in Figure 5, the blade 38 has one foot 39 only secured, as above described in the fibrous plate flange on the bottom plate.

In the form of the invention illustrated in Figures 6 and 7, the fibrous plate 40 has flanges 41, 42 formed therewith to which the shoes 43, 44 are secured, having comparatively small slots 45, 46 therein and longer elongated slots 47, 48 formed there with, the inner side edges of which are formed into racks 49 and 50 respectively, adapted to be engaged by gears 51, 52 on shafts 53, 54, which carry also larger gears 55, 56 in mesh with worms 57, 58 on a transverse shaft 59 having an operating handle 60 at one end. The shoes 43, 44 glide in grooves 61, 62 in the base-plate 68, and pins 64, 65 travel within slots 45, 46 to limit the movements of plate 40.

The waste remover blade 66 in this form, also of a stretched U-shape in side elevation, has its foot parts 67 attached to channeled foot flanges 68 having an inner thread adapted to, he engaged by a gear 69 on a stub-shaft 70 which carries within a chamber 71 of base plate 63 a worm wheel 72 in mesh with a worm 73 at the inner end of a shaft 74 extending throtwh the side of the base-plate 68, carrying alrnob 75. A great mechanical advantage exists between the worm pinions, worm wheels, and the gears, so that the worm pinions are turnable to move the fibrous plate, While conversely a great mechanical disadvantage exists, and trying re more the fibrous plats.

will result in parts breaking rather any motion, whereby an adjustable self holding feature is accomplished.

From the above description the operation of our device will be entirely clear, if it is desired to adjust the waste remover blade and the fibrous plate, this can be done by the proper operation of the shoes 25, 26 by the manipulation of wing nuts 34 in the form Figure 3, or by the proper manipulation of knob in the form illustrated in Figures 6 and 7. The plate in this form is independently adjustable by means of the n'ianipulation of handle 60.

It is to be understood that while we have shown the principal embodiment of our invention in the drawings, by way of example, changes may be made such as fall within the scope of the appended claims without departure from the spirit of our invention.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. A label punching machine comprising a pair of hollow punching dies, a fibrous plate adj ustably arranged beneath said dies, and a waste remover blade on said plate, and means for adjusting the relative positions of said fibrous plate and said waste remover plates.

2. In a label punching machine of the class described, a base plate, a pair of hollow adjustable punching dies above said plate, a fibrous plate on said base plate, means for adjusting the relative positions of bothplates, a waste remover blade, and means for adjusting the position of said blade relatively to said plate and punching dies.

3. In a label punching machine of the class described, a grooved base-plate, a fibrous plate adapted for displacement on said base, shoes on said plate sliding in the grooves of said base, and means for locking the parts in their relative adjusted po sitions, and an adjustable waste remover blade on said fibrousplate adapted to be operated and locked by said displacing means.

4. In a label punching machine having a pair of punching dies, a base plate having grooves formed therein. a fibrous plate slidably arranged above said base plate, shoes formed with said fibrous plate adapted to slide in the grooves of said base plate, means for adjusting the relative positions of both plates, and a waste remover blade guided in said shoes. and means for locking it in any of its adjusted positions.

5. In alabel punching machine, a base plate having grooves formed therein, a fi brous plate having shoes sliding in said grooves, a waste remover blade extending across said fibrous plate and having its ends attached to said shoes, said shoes being formed with elongated apertures having inner racks on one side, gears in mesh with said racks, shafts for said gears, worm wheels on said shafts within chambers formed in said base plate, worm pinions in engagement with said worm wheels, a shaft carrying said worm pinions and extending beyond the edge of said base plate, and a knob at the outer end of said rod, whereby an adjustment and holding of Waste remover blade and fibrous plate is accomplished by the mechanical disadvantage of said worm pinions to gears.

6. In a label punching machine of the class described, a grooved base-plate, a fibrous plate slidably arranged above said base-plate, shoes attached to said fibrous plate adapted to slide in the grooves of said baseplate, said shoes having pairwise arranged larger and smaller slots, racks on the inner side edges of said larger slots. gears in mesh with said racks shafts for said gears, larger gears on said shafts, worms in engagement with said larger gears, a transverse shaft for said worms, and a handle at one end of said shaft for displacing said fibrous plate relatively to the baseplate by the operation of gears on said shaft.

In a label punching machine a base plate having grooves formed therein, a tibrous plate having shoes sliding in said grooves, means for displacing said shoes and fibrous plate relatively to said base plate and holding the parts in their adjusted positions, and a waste remover blade extending across said fibrous plate having its angular ends attached to channeled foot flanges form with inner rac rs, gears in mesh with said racks, a shaft for said gears, worms 011 said shafts within a chamber formed in the base-plate, a worm in engagement with said worms, a. rod carryiiig said worm and extending beyond the edge of said base-plate and a knob at the outer end of said rod for allowing an adjustment of said waste remover blade, and means for holding the parts in their relative adjusted positions.

In testimony whereof we have ailised our signatures.
